Background Alkaptonuria is a rare autosomal recessive metabolic disorder with an incidence of 1 case in 250,000 to 1 million live births. This genetic abnormality involves the tyrosine metabolism pathway which results in homogentisic acid accumulation throughout various tissues, including the heart. The purpose of this study is to prospectively determine the prevalence of cardiovascular abnorma...
Background: This study investigated the effects of extremely low frequency (ELF) pulsed electromagnetic field (PEMF) radiation on the growth of bacterium Staphylococcus aureus (ATCC 25923) that plays a versatile role in infecting wounded tissues. The viability of these bacteria (number of live cells as colony-forming units (CFUs)) was measured before and after the ELF PEMF exposures to quantify...
Basement membrane (BM), a sheet-like form of extracellular matrix, surrounds most tissues. During organogenesis, specific adhesions between adjoining tissues frequently occur; however, their molecular basis is unclear. Using live-cell imaging and electron microscopy, we identify an adhesion system that connects the uterine and gonadal tissues through their juxtaposed BMs at the site of anchor c...
For most of us, genetic inheritance plays a limited role in determining our health. More important is where and how we live, work, and play -the quality of what we drink, eat, and breathe. From the time of conception, throughout development, and into early and late adulthood, environmental factors either directly impact biological tissues or influence gene expression and shape subsequent diseas...
Drosophila melanogaster plasmatocytes, the phagocytic cells among hemocytes, are essential for immune responses, but also play key roles from early development to death through their interactions with other cell types. They regulate homeostasis and signaling during development, stem cell proliferation, metabolism, cancer, wound responses, and aging, displaying intriguing molecular and functiona...
H uman organs and tissues differ in regard to their clinical and research uses and the regulatory legislation controlling their use. Organs such as livers and hearts are usually taken from donors who are brain-dead; in addition, kidneys can also come from live volunteers. Organs decay rapidly and need to be transplanted quickly. Surgeons and coordination teams in transplantation centres control...
Determination of hydrogen sulfide (H2S) in live cells and tissues is still a challenge for evaluating the key roles that H2S plays in physiological and pathological processes. In this work, a "turn-on" two-photon fluorescent (TPF) sensor for H2S is developed, in which carbon nanodot (C-Dot) was employed as a two-photon fluorophore due to its large two-photon absorption cross-section (σ), and AE...
Cryopreservation of immature testicular tissues is essential for increasing the possibilities of offspring generation by testicular xenografting for agricultural or medical purposes. However, successful production of offspring from the sperm involved has never been reported previously. In the present study, therefore, using intracytoplasmic sperm injection (ICSI), we examined whether xenogeneic...
This paper introduces a new direction in the field of artistic live coding where musical works are presented as pieces in the form of a live coding system. The system itself and the code affordances become equivalent to score system in an open musical work for strong improvisation.
